Exercise, Body Composition, and Functional Ability: A Randomized Controlled Trial

摘要: Context In women, age and the menopausal transition contribute to an increase of body fat a reduction lean mass associated with functional decline, affecting independent living. Background Sarcopenia adiposity in elderly has been increased mortality decline Purpose This study was conducted determine effect multipurpose exercise program on composition ability women living community. Design An 18-month single-blinded RCT comparing participants active control group from May 2005 through December 2007. Analyses were January 2008 July 2008. Setting/participants Two hundred forty-six (aged 69.1±4.0 years) independently area Erlangen–Nurnberg (Germany) participated study. Intervention Subjects ( n =123) performed special emphasis intensity but low-level requirements for training facilities materials. The 123 focused primarily well-being. Main outcome measures Body assessed by dual-energy x-ray absorptiometry. Further, strength evaluated using isometric techniques back legs. Aerobic fitness determined progressive-intensity treadmill test. Results After 18 months, significant effects favor increases appendicular skeletal muscle along reductions abdominal total fat. Significant performance also favored included enhanced maximum trunk-extensor leg press strength, power, timed up-and-go test, aerobic fitness. Conclusions A high-intensity produced improvements cohort Trial registration NCT00267839.
